螺桿式空壓機(jī)

。當(dāng)儲(chǔ)氣罐壓力降至0.5--0.6MPa時(shí)壓力開(kāi)關(guān)自動(dòng)聯(lián)接啟動(dòng)。 Introduce double screw type single stage compression air compressor is composed of a pair of parallel tooth rotor (or screw), Yin and Yang of rotation, inside the cylinder between the rotor alveolar air constantly  produce periodic changes in volume, the air is along the rotor axis by  suction side to the output side, screw air compressor suction,   compression and exhaust process. The inlet and outlet of the air   compressor are located at opposite ends of the shell, and the slot of   the Yin rotor and the tooth of the male rotor are driven by the main   motor. The motor drives the compressor directly, causing the crankshaft to rotate, and the connecting rod causes the piston to reciprocate,   causing the cylinder volume to change. Due to the change of pressure in the cylinder, through the inlet valve to make the air through the air   filter (silencer) into the cylinder, in the compression stroke, due to   the cylinder volume reduction, the role of compressed air through the   exhaust valve, the exhaust pipe, one-way valve (check valve) to storage tanks, when the exhaust pressure to achieve the rated pressure of 0.7   MPa is controlled by a pressure switch and automatic stop. The pressure switch automatically connects when the reservoir pressure drops to   0.5-0.6 MPa.  2. 旋葉式壓縮機(jī) Rotary vane compressor     每種型號(hào)的壓縮機(jī)對(duì)潤(rùn)滑油的要求都是不同的
